Abstract

L'invention concerne un mécanisme d'actionnement d'une boîte de transfert dans un véhicule automobile, permettant de changer de mode d'entraînement à deux roues motrices ou quatre roues motrices. Ce mécanisme comprend une première tige de commande 44 associée à une fourchette 58, et une seconde tige de commande 45 associée à une fourchette 70, l'extrémité 44e de la tige 44 coopérant avec une saillie 70a de la fourchette 70 pour empêcher la sélection d'un mode de fonctionnement à deux roues motrices pour une vitesse faible. L'invention concerne les mécanismes d'actionnement des unités de transfert des véhicules à deux roues et quatre roues motrices.The invention relates to a mechanism for actuating a transfer case in a motor vehicle, making it possible to change the drive mode to two-wheel drive or four-wheel drive. This mechanism comprises a first control rod 44 associated with a fork 58, and a second control rod 45 associated with a fork 70, the 44e end of the rod 44 cooperating with a projection 70a of the fork 70 to prevent the selection of 'a two-wheel drive mode of operation for low speed. The invention relates to actuation mechanisms for transfer units of two-wheel and four-wheel drive vehicles.
